<h1>保留字</h1>

<p>为了便于编程，CodeIgniter使用了一系列的函数和名称来完成操作。所以，有些名称不能被程序员使用。下面是不能被程序员使用的保留字列表。</p>

<h3>控制器名称</h3>
<p>因为你的控制器类将继承主程序控制器，所以你的函数命名一定不能和主程序控制器类中的函数名相同，否则你的局部函数将会覆盖他们。下面列出了已经保留的名称，请不要将你的控制器命名为这些：</p>
<ul>
 <li>Controller</li>
 <li>CI_Base</li>
 <li>_ci_initialize</li>
 <li>Default</li>
 <li>index</li>
</ul>

<h3>函数</h3>
<ul>
 <li>is_really_writable()</li>
 <li>load_class()</li>
 <li>get_config()</li>
 <li>config_item()</li>
 <li>show_error()</li>

 <li>show_404()</li>
 <li>log_message()</li>
 <li>_exception_handler()</li>
 <li>get_instance()</li>
 </ul>
<h3>变量</h3>
<ul>

 <li>$config</li>
 <li>$mimes</li>
 <li>$lang</li>
</ul>
<h3>常量</h3>
<ul>
 <li>ENVIRONMENT</li>
 <li>EXT</li>
 <li>FCPATH</li>
 <li>SELF</li>
 <li>BASEPATH</li>
 <li>APPPATH</li>
 <li>CI_VERSION</li>
 <li>FILE_READ_MODE</li>
 <li>FILE_WRITE_MODE</li>
 <li>DIR_READ_MODE</li>
 <li>DIR_WRITE_MODE</li>
 <li>FOPEN_READ</li>
 <li>FOPEN_READ_WRITE</li>
 <li>FOPEN_WRITE_CREATE_DESTRUCTIVE</li>
 <li>FOPEN_READ_WRITE_CREATE_DESTRUCTIVE</li>
 <li>FOPEN_WRITE_CREATE</li>
 <li>FOPEN_READ_WRITE_CREATE</li>
 <li>FOPEN_WRITE_CREATE_STRICT</li>
